Distribution Rack Installation

Unit and Rack
Preparation
To prepare the CoreBuilder 7000 family ATM switch and distribution rack
for installation:
1
Attach the mounting brackets onto the sides of the CoreBuilder 7000
family ATM switch using the mounting bracket screws (M4 x 8 Phillips).
2
Determine whether or not the distribution rack has threaded holes. If the
holes are threaded, “Mounting the CoreBuilder 7000 Family ATM
Switch” on page 3-6.
3
If the holes are not threaded, you must insert “G” clips. To determine
where to insert “G” clips, locate the top of a universal mounting hole
pattern on the left mounting rail. In the universal rail pattern, the spacing
between holes is 1/2 inch, 5/8 inch, 5/8 inch, and 1/2 inch. To find the top
of the pattern, locate the midpoint between any two holes that are
spaced half an inch apart. Figure 3-1 shows the universal mounting hole
pattern.

From the top of the universal mounting hole pattern, insert “G” clips in
the holes designated for the unit model.
5
Repeat steps 3 and 4 for the right rail. Ensure that you start on the same
hole space.
You are now ready to mount the CoreBuilder 7000 family ATM switch
into the distribution rack.
